I just picked up a new MacBook Pro 15" 2012 model. It's not the retina display. I already had a 2009 MacBook 13" white that I've been running for a few years. I was running BootCamp on my other MacBook, running Lion on the Mac OS side and Windows 7 on the Bootcamp side. I have an external monitor (LG) at home and a Samsung monitor at the office. I am using the mini display port to DVI adapter to run an external monitor between Lion and Windows 7 32bit just fine.
I plugged in the mini display port to dvi plug into the new MacBook Pro and poof..my external monitor worked just fine in Mountain Lion but when I reboot to the Windows 8 64 bit side of things in boot camp. No go. It doesn't even see the external monitor or anything I've plugged into it.
I know the cable is fine and the adapter is fine because it works on the Mountain Lion side of things. I'm thinking it is something to do with thunderbolt on the Windows side of things and that I'm missing a driver or something but I've tried for two days to get this thing working and I can't.
Does anybody have any ideas on how to get Windows 8 64bit to recognize an external monitor connected to it?
Thank you very much!
